You mean, it's impossible to go immediately, right? You can of course wait for one hour and go. There is nothing that would prevent you from doing it, right? So in the end we are talking about a one hour delay? In a game that plays over almost a year?
Well, everyone has their priorities, but tbh, the way the OP has written the original request, I would rather have Anthaum write new events instead.
And again, I don't mean I don't get the point of selecting pieces of clothing to wash separately. I do get it. Provided the game would add some really interesting reasons for it. Like what I wrote in my previous post.
My comments are only in relation to the OP's request. And I never had the problem with waiting the one hour when playing. But of course ymmv. Don't get mad at me. Not that I felt like anybody did.
